When I was in engineering school, I read about a Romanian doctor who used Kirlian Photography to supposedly detect disturbances in organ function before any Western test could. He was basically taking a “picture” of the back and if an organ function was disturbed, the associated back shu point would light up. Later I realized I could do the same thing using a point dectator with a roller electrode. I tried it and it worked. Basically it can detect autonomic disturbances before there is any pathology. Just have the patient hold the ground electrode like usual then roll the roller electrode up and down either side of the spine where the shu points are and see which ones show up. I did this on my stepson once and his lungs and kidneys showed up. the lungs were easy to understand since he had allergies. I also knew that the kidneys could also be involved with his allergies but though there might be another explanation. He was in his 20’s and was sexually active. That would weaken the kidneys and make them show up. I explained it to him and we had a good laugh. Using a roller electrode makes this test much easier and quicker. Just set the sensitivaty kind of low.
